IMAGE PICKUP APPARATUS, COLOR NOISE REDUCTION METHOD, AND COLOR NOISE REDUCTION PROGRAM - An image pickup apparatus includes an image sensor including a color filter having pixels of different colors arranged in a predetermined order and a demosaic processor. The image sensor receives a subject image and outputs an image signal including color signals of the different colors. The demosaic processor generates color signals of the different colors for each of pixels of the image from the image signal. The demosaic processor includes a generation unit and a noise reduction unit. The generation unit performs computation using a target color signal representing a predetermined target color signal included in the image signal and a predetermined different color signal so as to generate a color-related signal that associates the target color signal with the predetermined different color signal for a pixel of the target color signal. The noise reduction unit performs a noise reduction process on the color-related signal generated by the generation unit.

IMAGE PROCESSING APPARATUS AND METHOD, RECORDING MEDIUM, AND PROGRAM - The present invention relates to an image processing apparatus and method enabling to correct for camera shake given in image capturing, a recording medium, and a program. Discrete data pieces indicating shifts are obtained. The discrete data pieces are interpolated to obtain data indicating a shift every line. By the interpolation, a correction is calculated every line on the basis of the corresponding shift. On the basis of the corrections, pixel data read positions are determined. Pixel data is read based on the determined read positions. When a pixel to be read overlaps two pixels, pixel data of the pixel to be read is produced (interpolated) from pixel data pieces. In this manner, the effects of camera shake are corrected. The present invention is applicable to video cameras.

Image processing apparatus, image capturing apparatus, image processing method, and program - An image processing apparatus includes: an image synthesis unit generating a synthesized image by inputting images photographed at different positions and connecting strip areas cut from the images. The image synthesis unit generates a left-eye synthesized image applied to display a 3-dimensional image by connecting and synthesizing left-eye image strips set in the images and generates a right-eye synthesized image applied to display a 3-dimensional image by connecting and synthesizing right-eye image strips set in the images. The image synthesis unit performs a process of setting the left-eye image strip and the right-eye image strip in an allowable range of set positions of the left-eye image strip and the right-eye image strip used to generate the left-eye synthesized image and the right-eye synthesized image, which are at different observing points, applicable to display the 3-dimensional images by acquiring the allowable range from a memory or calculating the allowable range.

IMAGE PROCESSING APPARATUS, IMAGING APPARATUS, IMAGE PROCESSING METHOD, AND PROGRAM - An image processing apparatus includes an image evaluation unit evaluating properness of synthesized images as the 3-dimensional images. The image evaluation unit performs the process of evaluating the properness through analysis of a block correspondence difference vector calculated by subtracting a global motion vector indicating movement of an entire image from a block motion vector which is a motion vector of a block unit of the synthesized images, compares a predetermined threshold value to one of a block area of a block having the block correspondence difference vector and a movement amount additional value, and performs a process of determining that the synthesized images are not proper as the 3-dimensional images, when the block area is equal to or greater than a predetermined area threshold value or when the movement amount addition value is equal to or greater than a predetermined movement amount threshold value.
